Los Angeles: Australian actor Milly Alcock has become one of Hollywood’s fastest-rising stars, earning global recognition through her portrayal of young Rhaenyra Targaryen in HBO’s blockbuster fantasy series House of the Dragon. Now preparing for her biggest role yet in DC Studios’ Supergirl, the actress is opening up about the personal experiences that have shaped her journey—including the story behind her 20 tattoos.
During a recent promotional appearance ahead of the release of Supergirl, Alcock reflected on identity, self-expression, success, and the challenges that accompanied her sudden rise to international fame.
Why Milly Alcock Has 20 Tattoos
When asked about her collection of tattoos, Alcock revealed that she currently has around 20 pieces of body art and views them as a reflection of personal growth rather than permanence.
The actress explained that people often avoid tattoos because they worry about changing over time. For her, however, that evolution is precisely what makes tattoos meaningful.

As someone whose career requires constant transformation, she sees tattoos as a way to maintain a sense of individuality amid the demands of acting.
“My Body Is My Tool”
Alcock offered a unique perspective on why tattoos hold special significance for her as a performer.
She described acting as a profession where the body often becomes a vehicle for different characters, stories, and creative visions. Whether portraying a medieval royal in House of the Dragon or a superhero in Supergirl, she spends much of her career adapting herself to fit a role.
For that reason, the actress views her tattoos as something deeply personal—elements that belong solely to her regardless of the characters she plays.

Add Hunterfly on GoogleThe HBO fantasy drama quickly became one of television’s most talked-about series, turning the young actress into an international star almost overnight.
While the opportunity brought enormous professional success, Alcock revealed that it also triggered unexpected anxieties.
She explained that after experiencing such a major breakthrough, she developed a tendency to anticipate negative outcomes, almost as though her mind expected something bad to happen in response to something overwhelmingly positive.
Coping With Unexpected Anxiety
The actress described experiencing vivid scenarios in which everyday accidents or unexpected events would suddenly occur.
According to Alcock, these thoughts often involved highly detailed situations that seemed to emerge after her career reached a new level of success.
Psychologists often note that major life changes—even positive ones—can sometimes create stress, uncertainty, or heightened awareness of risk. Alcock’s reflections highlight how success can bring emotional adjustments that are rarely visible to the public.
She suggested that frequent travel may also contribute to those feelings, acknowledging that spending significant time on airplanes has occasionally heightened her awareness of potential dangers.
A Defining Year for the Actress
The interview arrives at an important moment in Alcock’s career.
After winning praise for her performance as young Rhaenyra Targaryen, she is preparing to make her debut as Kara Zor-El, better known as Supergirl, in DC Studios’ upcoming superhero film.
The role places her at the center of one of the entertainment industry’s most recognizable franchises and is expected to introduce her to an even larger global audience.
Industry analysts consider the casting a significant milestone, as DC Studios continues building its new cinematic universe under a fresh creative direction.
From Westeros to the DC Universe
Alcock’s transition from fantasy television to blockbuster superhero cinema reflects her growing influence in Hollywood.
Her performance in House of the Dragon established her as a standout talent capable of handling complex emotional material, while Supergirl offers an opportunity to showcase a different side of her acting abilities.
The move also underscores a broader trend in the entertainment industry, where streaming-era stars are increasingly crossing into major film franchises.
Looking Ahead
As anticipation builds for Supergirl, Alcock continues to attract attention not only for her performances but also for her openness about personal experiences and self-expression.
Her comments about tattoos reveal an artist who embraces change rather than fearing it—viewing each mark as part of an evolving story rather than a fixed identity.
For fans who first discovered her in Westeros, that perspective may help explain why Milly Alcock has quickly become one of the most intriguing young actors working in Hollywood today.
